Résumé
Due to the rising amount of plastic waste generated each year, multiple questions are emerging about theirharmful long-term effects on the environment, the ecosystems and human health. One possible strategy tomitigate these issues is to substitute conventional plastics by renewable materials fully biodegradable innatural conditions, such as poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and which can be producedfrom agro-industrial residues. The 3HB/3HV monomeric ratio depends on the kind of strains, the carbonsources, the nutrient limitation and its intensity used to promote the production of the copolymer as well asthe feeding strategy. In this dataset, a total of 19 production itineraries of PHBV production has been collectedin 4 interdisciplinary projects (EU GLOPACK, EU RESURBIS, EU ECOBIOCAP, ANR LOOP4PACK) . Available dataconcern the technical process descriptions, including the description of each step and the differentobservations measured during the agro-industrial by-products pretreatment (x, y, acidogenesis), PHBVbiosynthesis from glucose or volatile fatty acids and its recovery.This dataset uses a vocabulary defined with experts and described by PO² (Process and Observation Ontology)[1], an ontology dedicated at its core to the representation of transformation processes through the definitionof steps, the relations between those steps and the associated observations. In our case, specific domainvocabulary has been elicited and used to define precisely the different technologies used for the biomasstreatment and the biocomposites production. This vocabulary can be reused for other projects on the domain
